Abstract
A volatile dispenser is provided, including a reservoir containing a quantity of volatile liquid having a viscosity of no greater than 3.9 centipoises. Each of its individual components has a vapor pressure of no less than 0.008 mm Hg. The dispenser also includes an emanator fluidly coupled to the reservoir (either directly or through a wick) that is comprised of elongated oriented bonded fibers, the fibers being impermeable to the volatile material.
Claims20
A volatile liquid dispenser comprises:
- an impermeable reservoir containing a volatile liquid to be dispensed;
- a wick in fluid communication with the liquid;
- and
- an emanator in fluid communication with the wick, wherein the emanator has a horizontal length extending between opposite ends, and wherein the volatile liquid has a viscosity of no more than about 3.9 centipoises and further wherein the emanator is comprised of non-porous fibers that are thermally bonded together and oriented in parallel with and extend the length of the emanator.

A volatile liquid dispenser, comprising:
- an impermeable reservoir containing a volatile liquid to be dispensed, wherein the volatile liquid has a viscosity of no more than about 2.5 centipoises;
- a wick in fluid communication with the liquid;
- and
- an emanator in fluid communication with the wick, wherein the emanator is comprised of bonded, oriented, non-porous polyester fibers with a coating of high density polyethylene;
- wherein the fibers are bonded together by thermal fusion;
- wherein at least 95% by weight of all components comprising the volatile liquid have vapor pressures of no less than about 0.008 mm Hg at 20 degrees centigrade;
- and
- wherein the emanator has a thickness in a first direction orthogonal to a longitudinal extent of the fibers, wherein the thickness being no more than 3.5 mm, and a width in a second direction orthogonal to both the first direction and the longitudinal extent, wherein the width is no less than 10 mm.
